How to Check Fuel Consumption and Displacement When Buying a Car?

What does 215/60r17 tire mean?

The 215/60r17 tire means the tire's section width is 215mm, the aspect ratio is 60%, R represents the tire type code, which is a radial tire, and the rim diameter is 17 inches, indicating the tire is suitable for 17-inch rims. The national standard tire numbering includes section width, aspect ratio, tire type code, rim diameter, load index, and speed rating code. The aspect ratio means the tire's sidewall height is the tire's section width. The larger the aspect ratio number, the thicker the tire appears from the side, and the smaller the number, the thinner it appears. Thicker tires offer better comfort but poorer handling. Thinner tires provide better handling but poorer comfort and more road noise. Most family cars use tires with a larger aspect ratio, while most performance cars and supercars use tires with a smaller aspect ratio. Do not arbitrarily change tire sizes, as it will affect the car's handling and driving stability. Changing tire sizes will also make the vehicle fail the annual inspection. Tires are the only part of the car that contacts the ground, affecting the vehicle's driving stability and safety. Tires are rubber products, and rubber will age over time, so tires need to be replaced regularly. Generally, tires installed on a car can last four years. When buying new tires, always check the production date. Unused tires typically have a shelf life of three years. In addition to the model, tires also have the following common markings: Tire cord material: Indicated by Chinese pinyin, such as M for cotton cord, R for rayon cord, N for nylon cord, G for steel cord, and ZG for steel radial cord tires. Speed rating: Indicates the maximum speed the tire can carry a specified load under specified conditions. Letters A to Z represent speed ratings from 4.8 km/h to 300 km/h. Common speed ratings include: Q: 160 km/h; H: 210 km/h; V: 240 km/h; W: 270 km/h; Y: 300 km/h. Rim specification: Indicates the rim size compatible with the tire for practical use. In daily use, pay attention to the following points: Regularly check the tire surface for cracks, deformations, or other defects. Due to wear, the tread grooves gradually become shallower. If the tread wears out, it will lose its drainage and anti-slip functions, significantly reducing the car's performance. Small cracks can also lead to blowouts at high speeds. Additionally, remove stones stuck in the grooves promptly. Park on level ground whenever possible. Avoid parking on roads with thick, sharp, or pointed stones. Do not park near or in contact with petroleum products, acids, or other materials that can deteriorate rubber. After parking, avoid turning the steering wheel, as this accelerates tire wear. Do not splash water to cool tires. In hot weather or during high-speed driving, tires can overheat, and pressure may increase. In such cases, stop to let the tires cool naturally. Never release air to reduce pressure or splash water to cool the tires, as this can cause abnormal aging of the tread rubber. Avoid sudden braking. Try to minimize frequent or hard braking to prevent accelerated tread wear from dragging on the road.

What Causes Sudden RPM Increase in Neutral Gear?

Sudden RPM increase in neutral gear may be caused by slight throttle sticking. Below is relevant information about automotive transmissions: 1. Functions: (1) Change transmission ratio to expand the variation range of driving wheel torque and speed, adapting to frequently changing driving conditions while keeping the engine operating under favorable conditions; (2) Utilize neutral gear to interrupt power transmission, allowing engine startup, idling, and facilitating gear shifting or power output. 2. Components: (1) Housing: Used to install and support all transmission components and store lubricating oil. The housing should have sufficient rigidity with reinforced inner walls, featuring complex shapes and mostly being castings; (2) Transmission components: Refer to gears, shafts, bearings and other transmission parts. Shaft dimensions are determined through strength and stiffness calculations, primarily depending on stiffness. Since carbon steel and alloy steel have nearly equal elastic modulus, carbon steel is generally used. Alloy steel is only employed when gears and shafts are integrated or when shaft loads are severe.

Is the Tiggo 8 equipped with a domestically produced engine?

The engine of the Tiggo 8 is domestically produced, developed through a collaboration between Chery and AVL. The Tiggo 8's 1.6L turbocharged engine model is SQRF4J16, with a maximum horsepower of 197 HP, maximum power of 145 KW, maximum power speed of 5500 rpm, and maximum torque of 290 N.m. The 2.0L turbocharged engine model is SQRF4J20, with a maximum horsepower of 254 HP, maximum power of 187 KW, maximum power speed of 5500 rpm, and maximum torque of 390 N.m. For daily maintenance of the Tiggo 8's engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, choose SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions. For diesel engines, select CB--CD grade diesel engine oil according to mechanical load, with the standard not lower than the manufacturer's requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, leading to various engine problems. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and oil cannot pass through, the filter may burst or the safety valve may open, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. Small amounts remain suspended in the oil, while larger amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures normal engine operation but also extends the overall lifespan of the radiator and engine.
